The official lyrics to "Go Go Mario," translated into English from Japanese:

Today, full of energy, Mario is still running, runningGo save Princess Peach! Go!Today, full of energy, Mario runsToday, full of energy, jumping!Today, full of energy, searching for coinsToday, keep going, Mario!

Get a mushroom - it's Super Mario!Get a flower - it's Fire Mario!

Goomba! Troopa! Buzzy Beetle! Beat them all!Mario is always full of energy and strong!

[Spoken] The only one who can reverse the spell that has captured the Mushroom People is Princess Peach. But Princess Peach is hidden underground, in a far-off castle. Ah, the days of peace... if we could once more return to those days... to save Princess Peach and bring peace back to the Mushroom Kingdom, that is why Mario is on his journey today.

Today, full of energy, Mario is still running, runningGo and beat the Koopa tribe, go!Today, full of energy, Mario runsToday, full of energy, jumping!Today, full of energy, searching for coinsToday, keep going, Mario!

Get a star - become invincible!Quickly, go save Princess Peach!

Lakitu! Blooper! Cheep Cheep! Beat them all!Mario is always full of energy and strong!

Today, full of energy, Mario is still running, runningHe's made it to the castle and gets fireworks!Lightly sidestepping the Hammer Bros.Show the last of your power, Mario!It's been a long journey but it's nearly at an endYou've done it, you've done it! You've defeated Bowser!
